Abstract
The invention concerns an optical receiver comprising: a photodiode (102) coupled to the input of a trans-impedance amplifier (308) such that the trans-impedance amplifier receives the current (IPD) of the photodiode; a first comparator (112) adapted to compare an output voltage (VOUT) of the trans-impedance amplifier (308) with a threshold voltage (VTH); and a threshold control block (314) for generating the threshold voltage (VTH), wherein the threshold control block (314) comprises at least one capacitor coupled to the output (110) of the trans-impedance amplifier (308) via at least one switch.
